Abstract: 655,944. Moulding articles from pulp. MARGUERAT, G. Aug. 27, 1947, No. 23781. Convention date, May 23, 1944. [Class 87 (ii)] A pulp moulding machine comprises a hollow mould carrier 7 for a number of foraminous moulds 10 adapted to be lowered and raised by a cylinder 6 into and out of a pulp suspension 11. Suction for moulding and compressed air for ejection are supplied at 9 and 8. After moulding, the articles are raised on their moulds and a reciprocating receiver 13 with articlereceiving forming-pockets 14 is brought beneath them by a cylinder 20 and links 19, 16<SP>1</SP>, 21. The articles, e.g. receptacles, are then lowered into the pockets, compressed therein, and discharged thereinto by compressed air, the moulds then being raised and the receiver 13 moved to a position beneath suction extractors 25. These are lowered into the articles by cylinder 6<SP>1</SP>, suction applied at 9<SP>1</SP> and the articles on the extractors lifted from the receiver 13 which is then moved to the left. The articles on the extractors 25 then descend and are deposited on to a conveyer 26 by compressed air supplied at 8<SP>1</SP>. Figs. 8 and 9 (not shown) show two designs for the extractors 25. The pockets 13 may be perforated and lined with sheet rubber which, under the action of suction, compresses and smoothes the articles when suction is applied by the extractors and assists in removing water. Fig. 10 shows details of the mould carrier 7 which is divided into two chambers 32, 33 communicating respectively with the suction and air pipes 9, 8. Suction pipes depend into the bases of the moulds from the chamber 32 and the chamber 33 communicates with the moulds through holes 35. In a modification, Fig. 5, the extractors are dispensed with and the receiver 13 is inverted by rack and pinion 41, 40 as it moves to a position over the conveyer 26. The pockets 14 are perforated and the articles are ejected therefrom, bottom up, by compressed air supplied to the receiver 13. The pockets may be surrounded by rubber sleeves so that the compressed air acts only on the bases of the articles. The Specification as open to inspection under Sect. 91 'refers to a receiver with a removable bottom which would be arrested by a stop during the movement of the receiver which would then continue to the point at which the articles would be ejected. It is also stated that the receiver may move about a vertical axis and pass through a plurality of moulding stations. This subject-matter does not appear in the Specification as accepted.
